Be it known that l, CARL RUDOLPH linens,

a citizen of the United States, and o resi-v dent of Ozihlnni'l, countyof Alameda, and State of California, have invented a new and usefulElectrical Switch, of which the following is e specification.

The present invention relates to iniprovo ments in electrical switchesand its psrtic r ltl object is to provide at switch particularly adoptedor giving direction indicating signals in connection with motorvehicles. While designed for this purpose, it may however, be used inmany different ways and would be particularly adapted for z1dvertisingsigns and the like calling for :1

individual lights. It is proposed in the pres ent invention to use :iplanetary SjYStG-Ill for establishing electrical connections betweenvarious contacts. Further objects and odtnntng of my invention willappear as the s nciticstion proceeds.

The preferred form of my invcntion is illustrated in the accompanyingdrawing in h Figure 1 shows a plan View orv my ch, Figu. 2 a plain Viewwith the cover :1, horizontal section through the same taken along line3-8 oi?

The

pin (1.8) mounted with freedom of radial motion in the perforation (15)of case (2) and conveys freedom. of parallclmotion to all points itsegment (3) and sections {12 (13) and (14). Tlho springs (19) are soarranged that when octing'together upon sections (13} and (let) theforce resultant acts in the same plane and parallel to the radial motionof the pin (18}. I have in my planetary-switch provided both factorsabsolutely necessary, namely, "uniform pressure in uniform direction ofapplication. The section (11) is the largest one and occopies more thanonelmlif of the iiolc'internul gear, while the section {12) is thesmallest one and is arranged diametrically opposite to the centralportion of section (ll). The sections and (1 1-) are interposed betweenthe sections (11) and (12) on opposite sides of "the letter. All foursections sire insulated from one another as shown at (16), preferably byon air The large section (ll) is connected with a source of electricalenergy by means of the binding post (17) extending through the case intothe said section. This section (11) will be referred to es the livesection. The section (12) does not communicate withany port onelectrical circuit and may, therefore, be ed es the deed section. Thetwo s ctions (13) and 1%.) here incite]: referred to as thecontzictsections, make contact through sgfiiings (19; with. plates (21)which l t ter metallic connection with binding; posts (22), which lattcrform parts of two different light cir cuits.

Itwill be seen that when the drive near (1 i :otatcd by means of thehandle (9) the pinions revolve between the two gears and will estoblishelect-r col corn nections betv'een d erent sections of the internal "cardue the fact that the three pinions are electrically connected by meansof the retaining rings In the position shown in Figure 3, the pinions(25) and engage the live section (11), while the pinion the dead section(12).

An evident further advantage is due to thesuperior, yes almost perfeet balance of movable parts in stableequilibrium, which no outside movement or joltiug disturbs, provided thetwo arms of the handle (9) and are balanced in length and Weight.

teeth to the drive gear and 12 teeth to each pinion with rrespendingchanges in the number of nious and of contact sections. In this casethere would be a maximum. of five primary positions of thecontrol-lower. It is suiiicient to indicate the possibility Withoutgoing too far afield in these speci fications.
